2026 Taiwan Investor's Guide to US Stock Trading Platforms — Comprehensive Review of Fees and Services of the Top Five Brokerage Firms

Why Taiwanese Investors Need to Understand US Stock Trading Platforms

In recent years, the US stock market has attracted increasing attention from Taiwanese investors. However, unlike investing in Taiwan stocks, purchasing US stocks requires trading through a brokerage platform. Currently, the market includes international brokers that offer direct overseas accounts and local Taiwanese brokers providing omnibus services. Choosing the right trading platform directly impacts investment efficiency and trading costs.

Five Core Criteria for Choosing a US Stock Trading Platform

Making the right choice among numerous US stock trading platforms requires a comprehensive assessment from the following perspectives:

1. Funds Security and Regulatory Qualifications

The primary prerequisite for overseas investment is the safety of funds. It is crucial to verify whether the broker is regulated by reputable authorities such as the US FINRA, SIPC, Australian ASIC, etc. Brokers with these regulatory certifications will protect investors’ assets even in the event of bankruptcy.

2. Trading Instruments and Restrictions

Different brokers support different trading instruments. Some platforms allow options, margin trading, and short selling, while others have restrictions. It is essential to check the official website in detail before choosing to ensure the platform supports the investment products you need.

3. Trading Fee Structure

Most brokers charge per trade or per share. The key is to understand whether there are hidden costs beyond basic fees, such as additional charges for exceeding limits, monthly maintenance fees, etc. Promotional activities (like new account incentives) can also significantly reduce investment costs.

4. Chinese Language Support

Language barriers can easily cause issues. Choosing platforms that offer Chinese customer service, Chinese websites, and Chinese apps can greatly improve user experience and risk management efficiency.

5. Deposit and Withdrawal Efficiency and Methods

The speed of fund arrival directly affects trading efficiency. Understanding the supported deposit and withdrawal methods, processing times, and whether TWD (New Taiwan Dollar) is supported is vital for capital turnover.

Capital Needed to Start Investing in US Stocks

Important Clarification: Opening a US stock account at a regulated financial institution is completely free.

The minimum trading unit for US stocks is 1 share (compared to 1000 shares in Taiwan stocks), lowering the investment threshold. For example, a tech stock priced at about $600 requires only $600 to buy one share (without margin).

CFD Trading — An Option to Lower Investment Barriers

Besides traditional stock trading, CFDs offer leveraged trading using margin, allowing investors to control larger assets with less capital.

CFD Trading Cost Components:

• Spread: The difference between buy and sell prices, the main cost, increasing with trade size
• Commission: Some platforms charge a percentage of the trade amount or fixed fee
• Overnight Fees: Financing costs for holding positions overnight, calculated as: number of lots × contract size per lot × opening price × daily overnight rate(%)

Risk Warning: Leverage trading amplifies both gains and losses. Proper stop-loss mechanisms and risk management strategies are essential.
